EMERGENCY-RIM FOR VEHICLE-WHEELS.

Specification of Letters Patent. Application filed November 15, 1910.Serial No. 592,545.

Patented Mar. 3, 1914.

To'all whom it may concern:

Be it known that I, ALEXANDER TURN- BULL, of the firm of Alex. Turnbull& Co. Ltd, of St. Mungo street, Bishopbriggs, Glasgow, Scotland, haveinvented certain new and useful. Improvements in Emergency-Rims forVehicle-\Vheels, of which the following is a specification. Y

My invention relates to improvements in emergenc .rims for vehiclewheels and consists in tie construction of the rim and ameans of fixingsame to the wheel of a motor car or other vehicle, after the removal ofthe ordinary tire which may have become damaged and a means ofpreventing creeping or side play between the emergency rim and the wheelof the motor car so that the extreme diameter of my emergency rim whenapplied to the motor or other vehicle wheel will be practically equaltothat of the vehicle wheel before being damaged. 7

In order that my invention may be properly understood and readilycarried into effect, I have hereunto appended drawing wherein Figure 1is a front view of a vehicle wheel illustrating one method of attachingmy emergency rim thereto; Fig. 2 is a part section along line 2-2 ofFig. 1 in larger scale; Fig. 3 is a part front view in larger scale ofFigs. 1 and 2; Fig. 4 a plan view of Fig. 3 looking down, but with theemergency rim and male member removed and showing locking washerinterlocking with the wheel rim; Fig. 5 a similar view to Fig. 4 withthe locking washer in unlocked position.

In carrying out my invention as applied to a motor car wheel, after theremoval of the damaged tire, I provide a rim D of slightly largerdiameter than the rim B of the car wheel and on suitable tire or tread,but preferably one of an elastic nature and whose extreme diameter is'practically equal to the diameter of the car' wheel and penumatic orother tire before bein damaged.

In the space etween the rim 1) and the car wheel rim B are arranged sixor other number of devices which act as struts and ties consisting oftwo members which are screwed male and female, and are adjustablelengthwise to said space between the two runs, said rims being at thetime concentric with each other, one end of said struts and t es, beingmade to fill the space between the inner edges of the car wheel rim, soas to which is carried any end so that it may be freely turned in a holeor recess in the locking washer F, shown more particularly in Fig. 2,the said washer F being so formed that it can be readily dropped inbetween the inner edge of the rim B of the Wheel of the car or othervehicle and lifted out, but when turned by means of a spanner through 90so that the extensions J of the washer F lie under the rim and theprojections I cause the rim to be slightly forced apart until turnedpast the center line, and consequently becomes locked with the turned inedges of the car wheel rim until the spanner is again used to releasethe same, as seen more particularly in Figs. 4 and 5. will be seen thatthe construction enables the device to act both as a strut and a tiebetween the two rims D and B. The lower half of Fig. 1 shows moreparticularly the position of the emergency rim just after having beenslipped over the rim of the vehicle wheel and ready for attachment whilethe upper half shows the position of the emergency rim after beingattached to the vehicle wheel rim. To prevent creeping of the emergencyrim around the vehicle wheel, I provide a pin or bolt G which may beinserted into or through the usual air valve hole in the vehicle wheel,as shown more particularly in Fig. 2, the upper head or end of said pinG entering into a recess H at the bottom end of strut and tie, as shownin Fig. 2.

I claim:

1. In an emergency wheel for vehicles comprising a rim of largerdiameter than the rim of the wheel proper, a plurality of supportspermanently carried by said emergenoy rim; each of said supportsconsisting of three members, one of said members being rigidly connectedto the inner periphery of the emergency rim, the second member adaptedto engage between the beads of the main rim when in looking position andto be In this arrangement it disengaged from said main rim when turnedapproximatel 90 relative to said position; the third mem er being a bolthaving threaded connection with the first member and being provided withan enlarged flange at its inner end, and a circular recess in saidsecond member for engaging with said flange, and means on said thirdmember for re volving it relative to the other two members.

2. In an emergency wheel for vehicles comprising a rim of largerdiameter than the rim of the wheel proper, a plurality of supportspermanently carried by said emergency rim; each of said supportsconsisting of three members, one of said members being rigidly connectedto the inner periphery of the emergency rim, the second member adaptedto engage between the beads of the main rim; the third member beingconstructed to engage directly with the two other members in order-tohold them rigidly and permanently together and to adjust the distancebetween them, said third member having threaded connection with saidfirst member.

In testimony whereof I affix my signature in presence of two witnesses.

ALEXANDER TURNB'ULL.
